<Computer Controlled> Lightning Surge Simulator
LSS-15AX series
GENERAL
Surges represent transients that might be induced in cables by lightning. By their nature,
fairly high energy charges may easily damage or upset unprotected electronics circuits
and components. Surges are not a new problem. Many companies have been testing their
products at various stages of the products life: design tests, qualification tests, production
tests and diagnostic tests. The advance of surge suppression devices and technique does
not lessen the importance of surge testing, but rather increases it, as the requirement to
reduce power consumption and to increase the operational speed of semiconductors has
become more demanding. In addition, the issue of surge testing is attracting renewed
interest since this form of immunity is now a must for almost all electronic products for
access to the global market.
FEATURES
Fully compliant with the requirements called for in the 2nd edition of IEC 61000-4-5 standard,
the LSS-15AX series simulators provide a testing facility for up to 15kV test voltage without
sacrificing safety and ease of use. The LSS-15AX simulators generate the two combination
pulses 1.2/50 µs (8/20 µs) and 10/700 µs (5/320 µs)
Fully programmable and easy to use simulator that meets and far exceeds the
IEC 61000-4-5 (2nd edition) requirements
● 15kV testing
● Advanced safety
● Flexible test sequencing with Program Mode

MODEL : LSS-15AX-A1A
OUTPUT WAVEFORMS EXAMPLE
Voltage surge waveform: 1.2/50μs
Voltage: 4kV V:1kV/Div. H:10μs/Div
Current surge waveform:8/20μs
Current: 2000A V:500A/Div H:10μs/Div
Highly repeatable and exact waveform. A new methodology has achieved an improvement in actual output waveform.
The times to half-value, to say, 50 microseconds, have very limited reduction when the pulses are coupled to the power line CDN,
compared to the original waveform measured at the generator output itself.
FUNCTIONS
①Peak level monitor
Values of the actual peak
amplitudes are monitored
and shown for both voltage
and current.
①
②Automatic stop function by
detecting a breakdown
The simulator automatically
stops generating the pulses
if the peak current measured
exceeds a limit, which can be
freely set as the threshold
②
PANEL EXPLANATION
Emergency stop button
This button, easily accessible and placed
on the front panel, enables the operator to
stop the generation of high voltages
anytime he desires. Simultaneously
power supply to EUT turns off.

Safety interlock
A safety interlock is provided
through the special design
high voltage connector. The
high voltage circuitry never be
activated when the connector
is not correctly positioned or
not firmly locked.
Very intuitive settings can be done by the
assistance of the well configured
user-interface consisting of a 5-inch LCD,
ten-key, functions keys and others.
Coupling modes are graphically shown,
allowing the operator to select the desired
mode and allows easy reference of
settings when the test is in progress.
Memory card (option)
A PCMCIA memory card, which is
very common to notebook PCs, is
adopted. Test log and setting and
screen hard copy files can be
stored and retrieved.
